Definitions

• the invention relates to novel thiocarbonates having fungicidal and fungistatic effects, to the use of the compounds as fungicidal and fungistatic agents, and to methods of preparing the same.
• active agents having fungicidal effects are tetramethylthiuram disulfide, N- trichloromethylthio-4-cyclohexene-1 ,2-dicarboximide, and 5ethoxy-3-trichloromethyll ,2,4-thiadiazole.
• the invention therefore relates to new compounds of the above formula, to their use as fungicidal and fungistatic agents, and to methods of preparing the compounds.
• the compounds of the invention are particularly effective against fungi causing damping-off disease which are very difficult to control, such as Pythium ultimum. Another advantage is the excellent tolerance by plants to the use of these compounds.
• novel compounds may be employed alone or in mixtures of several active agents. Furthermore and optionally, other fungicides, nematocides, herbicides, seed disinfectants or other parasite control agents may be added, depending on the desired purpose.
• the compounds are preferably used in the form of compositions, such as powders, spreadable compositions, granulates, solutions, emulsions or suspensions, with added liquid and/or solid carriers or diluents, and optionally with wetting, adhesion improving, emulsifying and/or dispersing agents.
• Suitable liquid carriers are water, mineral oils or other organic solvents such as xylene, chlorobenzene, cyclohexanol, cyclohexanone, dioxan, acetonitrile, ethyl acetate, dimethylformamide and dimethylsulfoxide, and others.
• Solid carriers which are suitable include limestone, kaolin, chalk, talcum, attaclay and other clays as well as natural or synthetic silica.
• surfactants there may be mentioned the salts of lignosulfonic acids, salts of alkylated benzenesulfonic acids, sulfonated acid amides and their salts, polyethoxylated amines and alcohols.
• dyes such as neofuchsine and others may be admixed in order to impart a clearly visible color to the treated seeds.
• the proportion of the active agent or agents in the compositions may vary within limits, the actual concentration of the active agent in the composition being determined mainly by the rate at which the composition is intended to be used for soil or seed treatment.
• the compositions may contain between about 1 and percent by weight of the active agent and about 99 to 20 percent of liquid or solid carrier and optionally up to 20 percent surfactants in the form of an emulsion or of a solid composition.
• Suitable acid acceptors are, for example, tertiary organic amines, such as triethylamine or pyridine and others, inorganic bases, such as alkali metal hydroxide or carbonate and others, or the gammadimethylaminopropanol employed as a reactant which is then used in a correspondingly greater amount.
• the reaction is preferably carried out with the use of an inert solvent, for example, an ether or a liquid hydrocarbon and the like, either as a single-phase or a two-phase reaction, the latter with the addition of nonmiscible liquids, for example, water and an organic liquid not miscible with the same.
• an inert solvent for example, an ether or a liquid hydrocarbon and the like
• nonmiscible liquids for example, water and an organic liquid not miscible with the same.
• the reaction proceeds preferably in the temperature range of about 0 to 100C, but it can be carried out also at higher and lower temperatures.
• the salts may be prepared by the action of an organic or inorganic acid on the thiocarbonate.
• suitable acids such as mineral acids, monoor polycarboxylic acids and sulfonic acids may be considered of which the following are mentioned: hydrochloric acid, sulfuric acid, formic acid, propionic acid, valeric acid, oxalic acid, malonic acid, succinic acid, cyanoacetic acid, chloracetic acid, dichloracetic acid, trifluoracetic acid, benzoic acid, furan-2-carboxylic acid, p-toluenesulfonic acid, methanesulfonic acid, thioglycolic acid, citric acid, and the like.
• solvents such as water, ethers, alcohols or liquid hydrocarbons may be employed.
• the reaction temperature is not critical. After the reaction, the salts formed are recovered in a manner known in the art, for example, by suction filtration.
• the salts may also be prepared advantageously in a single stage process in which gammadimethylaminopropanol is reacted with chlorothioformic acid esters with or without solvent at about 20 to 100C, wherein the aminoalcohol derivative itself acts as an acid captor.
• 0.15 mole chlorothioformic acid ester is dissolved in 200 ml of absolute ether.
• 0.15 Mole gamma-dimethylaminopropanol in 200 ml of absolute ether is added slowly dropwise with stirring at -36C. Stirring is continued for 2 hours and the resultant precipitate is filtered off with suction and dried over phosphorus pentoxide. The yields are between 85 and 95 percent of theory.
• the free bases are soluble or very soluble in organic solvents such as ether, ethanol, acetone, benzene, chloroform, acetonitrile, ethyl acetate, dimethylformamide, dimethylsulfoxide, pyridine and the like, whereas the salts dissolve well or very well in water, methanol, ethanol and chloroform.
